Special Issue Information

Dear Colleagues,

Integrated pest management concept (IPM) is basically aimed to optimize pest management in an economically and environmentally sound manner, accomplished by the harmonized use of multiple tactics to ensure constancy of agricultural production and keep pest damage below the economic threshold. In other words, IPM should be efficient, protecting the environment, be sustainable, combining many control methods with chemicals use as a last option and considering economic threshold. There are five main principles of IPM, namely: i. Prevention measures, ii. Monitoring, iii. Economic threshold, iv. Promote alternative non-chemical methods and v. Reducing side effects on non-target organisms.

The contribution to this Plants special issue will be focused (but not limited) on the following topics as a review or new development research papers: cultural practices, control methods, pesticides uses reduction and zero residues, sublethal effects, pest monitoring, resistance management, economic aspects related to IPM, AI for decision support and all studies globally related to IPM. Field studies are the most welcomed. The pest is used here in his broad meaning which include diseases, insects, mites and weeds.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The current work aims to establish an integrated pest management strategy using Hyperaspis trifurcata Schaeffer (Coleoptera: Coccinellidae) to control Dactylopius opuntiae Cockerell (Hemiptera: Dactylopiidae) and to assess the side effects of pesticides commonly used on this predator. The first part of this study was performed under controlled conditions at two temperatures with three prey densities and two release rates for 83 days. Under field conditions, a survival time test was conducted in a screen house (1.2 ha), where a total of 5700 predators were released on 1425 cactus plants and then monitored for a period of 23 weeks. Furthermore, eight pesticides were tested on H. trifurcata in laboratory conditions at five rates in order to define the lethal doses. Under controlled conditions, the effect of temperature on predation was not significant until 27 days after release. However, the prey density significantly impacted the predation rates from the 10th to 27th day after release (p < 0.001). The predator release rate significantly affected predation starting from the 15th day after release. The lowest median survival time based on Kaplan–Meier tests was obtained at 30 °C (the high temperature) for eight predators/cladode (27 days), but the highest was at 26 °C (the low temperature) for four predators/cladode (63 days). Depending on cochineal infestation, the effect of temperature significantly increased the predation rate from the 10th to 49th day after release, but only at a high density (50 colonies/cladode). Under field conditions, the effect of the infestation level on the survival function was significant (Log-Rank p < 0.05), and the median times were 111 and 130 days after release for low and high densities, respectively. Acetamiprid, Vaseline oil, black soap, copper oxychloride, and paraffin oil were highly toxic to H. trifurcata (>84% of mortality), and the LD50 values ranged from 2.3 to 69.6% of the recommended rate. For Mancozeb at the recommended dose, the mortality rate was low (<2%). The large-scale release of H. trifurcata would be successful in the Near East and North Africa (NENA) region, provided that the use of the mentioned pesticides is avoided or at least reduced.

Soybean (Glycine max (L.) Merr.) is one of the most profitable crops among the legumes grown worldwide. The occurrence of rust epidemics, caused by Phakopsora pachyrhizi, has greatly contributed to yield losses and an abusive use of fungicides. Within this context, this study investigated the potential of using a phosphite of nickel (Ni) and potassium (K) [referred to as induced resistance (IR) stimulus] to induce soybean resistance against infection by P. pachyrhizi. Plants were sprayed with water (control) or with IR stimulus and non-inoculated or inoculated with P. pachyrhizi. The germination of urediniospores was greatly reduced in vitro by 99% using IR stimulus rates ranging from 2 to 15 mL/L. Rust severity was significantly reduced from 68 to 78% from 7 to 15 days after inoculation (dai). The area under the disease progress curve significantly decreased by 74% for IR stimulus-sprayed plants compared to water-sprayed plants. For inoculated plants, foliar concentrations of K and Ni were significantly higher for IR stimulus treatment than for the control treatment. Infected and IR stimulus-sprayed plants had their photosynthetic apparatus (a great pool of photosynthetic pigments, and lower values for some chlorophyll a fluorescence parameters) preserved, associated with less cellular damage (lower concentrations of malondialdehyde, hydrogen peroxide, and anion superoxide) and a greater production of phenolics and lignin than plants from the control treatment. In response to infection by P. pachyrhizi, defense-related genes (PAL2.1, PAL3.1, CHIB1, LOX7, PR-1A, PR10, ICS1, ICS2, JAR, ETR1, ACS, ACO, and OPR3) were up-regulated from 7 to 15 dai for IR stimulus-sprayed plants in contrast to plants from the control treatment. Collectively, these findings provide a global picture of the enhanced capacity of IR stimulus-sprayed plants to efficiently cope with fungal infection at both biochemical and physiological levels. The direct effect of this IR stimulus against urediniospores’ germination over the leaf surface needs to be considered with the aim of reducing rust severity. Full article
